imgstamp verifies that a photo is an authentic original captured on your device, then seals it with a cryptographic watermark. Pick any photo from your library. imgstamp checks the camera metadata, timestamps, and device signature to confirm it was taken on your device — not transferred, screenshotted, or edited. Verified photos are stamped with a gold seal and signed QR code. Anyone can scan the QR code to confirm the photo's authenticity — verification happens in the app or in the browser. No accounts. No uploads. No tracking. Everything happens on-device.
